[EBB Sightings] pine siskins in Montclair

Yes, believe it or not I have seen pine siskins at my feeder!    
Several days ago I saw what I thought was a p.s. but was skeptical  
since my sighting was brief and this is not the time of year to see  
these unpredictable birds in this area.  Then one hit our window a  
few days ago while I was not home but my non-birding husband  
identified it as a siskin from the picture in the Sibley guide.  The  
bird did fly away.  Then this afternoon I saw 2 at my kitchen window  
feeder.  I only had about 4 sightings all winter/spring this year in  
my yard.  Wonder where these 2 came from?
